pointcloud_storer_ros

Build Status License: MIT

ROS package for storing pointclouds and poses

The demo assumes that a portion of the scan data has been acquired, so the scan data is extracted with the pointcloud_angle_filter node in amr_navigation_utils_ros package

Environment

  • Ubuntu 20.04
  • ROS Noetic

Dependencies

Install and Build

# clone repository
cd /path/to/your/catkin_ws/src
git clone https://github.com/ToshikiNakamura0412/pointcloud_storer_ros.git
git clone https://github.com/ToshikiNakamura0412/icp_matching_ros.git

# build
cd /path/to/your/catkin_ws
rosdep install -riy --from-paths src --rosdistro noetic       # Install dependencies
catkin build pointcloud_storer_ros -DCMAKE_BUILD_TYPE=Release # Release build is recommended

How to use

roslaunch pointcloud_storer_ros pointcloud_storer.launch
